For him, the rewarding part about touring isn39。s Liaoning province, decades ago. The solider gave the old man a handmade saddle when they bid farewell. The story inspired Nasun to write Carved Saddle, a song that later became one of his most popular numbers. Now, every year, Nasun recruits young singers and dancers for the troupe. The troupe has also designed a new repertoire, which is mostly based on the daily lives of Mongolian people, especially the lives of nomadic families, and has bined contemporary musical elements with folk songs of the region. Haimu, a 25yearold khoomei (a local variant of overtone singing) singer, joined the troupe three years ago. Along with a sixmember band, he performs fast songs and soft ones that he writes－ all while playing the horsehead fiddle.Although I learned the piano since childhood and grew up listening to various kinds of music, to me, the folk music of Inner Mongolia is the root, he says. Performing in remote villages is pleasant. I feel at home on the boundless grasslands, and the warm people there make me feel fulfilled. The first round of spring auction season in Beijing ended last week, but it failed to create much spring in the art market. Although two pieces of Chinese painting fetched more than 100 million yuan, the decline in trading volume and sa le rate showed a downturn this year. In the ―Grand View: Chinese Painting Highlight‖ session at China Guardian 2022 spring auctions, Pan Tianshou’s representative work Eagle, Rock and Flora hit a record auction price of 279 million yuan, while Li Keran’s masterwork Jinggang Mountain fetched million yuan, an unexpected high in recent years. However, the trading volume fells to billion yuan from billion yuan in the same period the year before. The Huangchen 2022 Spring Auctions, which recorded million yuan in total sales, experienced the same. The section number went down to 5 from 12 pared to last year. According to expert Shao Jianwu, the art market did not attract much excitement this year due to the booming stock market and the persistent problems of fery and fake deals. The two pieces of Chinese painting notched up high price this spring due to their own value not due to a revival in the market. The successful transaction of two works with a hammer price of more than 100 million yuan once again confirms that valuable and rare works of high quality always earn the longlasting high price. Chinese painting and calligraphy is still the pillar of the market. However, the overall sales rate has dropped slightly, which reflects the demand for the ordinary auction goods has weakened,‖ said the president of China Guardian’s Hu Yanyan. Besides, the entry of new buyers also makes certain changes to the direction of purchasing. In a word, the overall market trend is very unpredictable. Although China Guardian 2022 Spring Auctions has achieved remarkable results, it does not mean that the market has walked out of the predicament. We still have to wait for the big economic boom to invigorate the art market.‖ Even so, the hot pursuit of some special items appeared this spring. A special session of China Guardian Spring Auctions titled ―Fine Gilt—Bronze Buddhist Images‖ achieved a great de。80s. We sat on the back of pickup trucks for hours. The sky was blue, and we couldn39。畢業(yè)設(shè)計是對大學(xué)四年所學(xué)知識的一次綜合性檢測， 在設(shè)計的過程中，我學(xué) 會有針對性的查一些需要的中英文資料，并對傳感器理論、單片機(jī)理論、自動控制原理 等方面的知識進(jìn)行了系統(tǒng)的學(xué)習(xí)，在鞏固了專業(yè)知識同時也學(xué)會了很多新的東西，了解了很多前沿學(xué)科的知識。 對整個系統(tǒng)進(jìn)行聯(lián)合調(diào)試，使系統(tǒng)達(dá)到本次設(shè)計的設(shè)計要求。要使酵母的繁殖與哀減，麥汁中糖度的消耗和雙乙酞等雜質(zhì)含量達(dá)到最佳狀態(tài) ，必須嚴(yán)格控制發(fā)酵各個階段的溫度。若為正溫度， Flag 為 0；若為負(fù)溫度， Flag 為 1； ② Read Temperature():溫度讀取函數(shù) ， 調(diào)用 Read Temperature()函數(shù)可以讀取出第 n+1 個通道的溫度值，并將此溫度值返回 ； ③ abj_dat():顯示數(shù)據(jù)處理函數(shù) ，它 將讀取第 m+1 個通道上的溫度值，并將該數(shù)值各位上的數(shù)據(jù)存儲到顯示緩沖區(qū)。 圖 DS18B20 讀溫度程序流程圖 DS18B20 讀溫度程 序流程圖如圖 所示，首先通過初始化程序?qū)慰偩€進(jìn)行復(fù)位，然后跳過內(nèi)部序列號讀取，啟動總線上所有的 DS18B20 進(jìn)行溫度轉(zhuǎn)換。 繼電器的特性參數(shù)包括輸入和輸出參數(shù)， 主要的參數(shù)為 額定輸入電壓 、 額定輸出電流 、 浪涌電流 。繼電器是一種電子控制器件，它具有 控制系統(tǒng)（又稱輸入回路）和被控制系統(tǒng)（又稱輸出回路），通常應(yīng)用于自動控制電路中，它實際上是用較小的電流控制較大電流的一種開關(guān)。 控制電路 在本設(shè)計中，被測溫度信號經(jīng)采樣處理后，還需要通過單片機(jī)系統(tǒng)的 口輸出用以控制保溫箱的溫度，通過這種方式達(dá)到控制的目的。 電源采用 220V 交流電路電容 C1 降壓。 圖 上下限溫度報警電路 啤酒發(fā)酵罐內(nèi)部麥汁溫度正常時，接在 SKD1 的電接點溫度計開路， VT1 基極無偏流而截止，發(fā)光二極管 VD5 不發(fā)光，音樂片 IC2 不被觸發(fā)；接在 SKD2 上的控制下限溫度的電接點溫度計接通， VT3 基極和發(fā)射極短路， Ib 等于零， VT3 截至，發(fā)光二極管 VD6 不亮， IC3 音樂片不觸 發(fā)。如圖 所示，為按鍵接口電路。鍵盤的工作方式選取的原則是：既要保證能及時響應(yīng)按鍵的操作，又不過多的占用 CPU 的工作時間。由于 74LS164 在低電平輸出時，允許通過的電流達(dá) 8mA，故不 必添加驅(qū)動電路，亮度也比較理想。連接電路如圖 所示。 ?
